“…Since steel plays a crucial role in petroleum industry, companies have prioritized finding ways of protecting steel rather than replacing it by other materials. Some of the ways consist of alloys, coatings, special treatments or inhibitors [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], in which the inhibitors have been demonstrated possessing the most suitable advantages. Most of today’s commercial corrosion inhibitors are amine-based as well as its derivatives.…”

The main aim of this study is to investigate Aganonerion polymorphum leaf-ethyl acetate extract (APL-EAE) and its inhibiting effect for steel in ethanol fuel blend. The immersion test, electrochemical and surface analysis techniques were successfully carried out in this research. Scanning electron microscope images indicated that the ethanol fuel blend induced pitting corrosion of steel. Remarkably, the surface of the sample containing 1000 ppm APL-EAE is smoother than the others submerged in different conditions. The electrochemical impedance spectroscopy result shows that APL-EAE has formed a good protective layer, preventing corrosive factors from hitting the steel surface. The potentiodynamic polarization data argue that the corrosion inhibition efficiency was strengthened with the increase of APL-EAE concentration. The Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy demonstrated less intensity of Fe peaks, higher intensity of C1s peak and the appearance of organic peaks (N1s, P2p, O1s) from specimens with and without APL-EAE addition. Therefore, the results suggest the formation of the protective film on steel surface and affirm that APL-EAE has served as an effective corrosion inhibitor for steel in ethanol fuel blend.

“…A quantitative analytical method was used to calculate the corrosion rate of each specimen based on the predicted weight change of low-carbon steel. The corrosion rate of specimen can be calculated using the equation [ 27 ] of:

where C r is the corrosion rate of the low-carbon steel specimen (in mm/y), W L is the weight change of the low-carbon steel specimen (in mg) and t is the immersion time (in h),

is the density of the low-carbon steel specimen (in g/cm 3 ).…”

Understanding the corrosion rate of metallic building materials is very important to maximize their beneficial use of public facilities. Direct measurements of the weight change and corrosion rate would be time consuming and expensive. This study aims to develop new empirical models based on the experimental data of testing 25 specimens immersed in five different environments for predicting the weight change and corrosion rate of the low-carbon steel. Using the equation developed based on the correlation between corrosion rate and chloride ion concentration is able to predict the corrosion rate of low-carbon steel at the limited chloride ion concentration. An increase in the trend lines of plotting the modeled and measured weight change of low-carbon steel versus immersion time is very similar to each other and progressively increase with increasing of the NaCl concentration. The corrosion rate of low-carbon steel increases from 0.202 to 0.286 mm/y with increasing of the NaCl concentration from 0 to 5% (w/w) in aqueous solution. The weight change and corrosion rate of the steel material are predicted using the new empirical models to contribute to the most reliable applications of low-carbon steel building materials in the future.

“…Sulfur species are among the most undesirable constituents in crude oil since they decrease the quality of the products. In addition, they can cause catalyst poisoning and corrosion of the processing equipment as well as various problems related to product odor and storage stability. − Sulfur can have an effect in crude oil fouling, with thiols, sulfides, and some condensed thiophenes to be considered as the most problematic . Free sulfur, disulfides, and thiophenol have been found to promote sludge formation, while the presence of hydrogen sulfide is extremely corrosive at high temperatures. , A major problem in the refinery heat exchangers is the formation of corrosion fouling due to chemical reactions triggered by sulfur compounds in crude oil on metallic surfaces.…”

With the depletion of conventional resources, heavier and more sulfur-rich crude oils come into the focus of interest. However, the utilization of such feedstocks is extremely undesirable since their high sulfur content causes corrosion fouling, catalyst poisoning, and emissions of toxic pollutants into the atmosphere. As known catalyst poisoners, sulfur-containing compounds are also suspected to play an important role in crude oil fouling, that is, the formation of undesired solid deposits. To overcome these problems, insightful knowledge on the chemical composition of the sulfur-containing compounds on a molecular level and their behavior is necessary. Here, fouling reactions of a gas condensate were simulated in the laboratory under atmospheric and inert conditions, with special focus on sulfur-containing compounds, and the resulting mixtures were analyzed by using sophisticated analytical methods such as ultrahigh-resolution mass spectrometry and electron microscopy. The results indicate that sulfur-containing compounds decompose at elevated temperatures, partly by a radical-induced mechanism. Furthermore, the resulting intermediates show a limited stability in the presence of oxygen.
